bon or bar passes to a suitable cutting mechanism (not shown) thatdivides it trans I versely into brick sizes. llhe ornamenting. mechanismis so mounted as to operate on the clay-ribbon as the latter passes fromthe die-plate to the cutting met hanism.

Directly in front of the mouth ofthe dieplate are the two marginalplowing pins 3, one on each side. Each pin is clamped between the plates4 (Fig. 9) adjustably secured to the bracket attached to the head 1 justabove the die-.plate. Each of these pins 3 plows in the upper i'ace ofthe clayribbon the marginal furrow'a (Fig. 10) extendingparallel withthe longitudinal corner of the ribbon. By adjusting the pin between theclamping plates 1 the depth of the marginal furrow and its distance fromthe longitudinal corner of the ribbon can be regulated. In theproduction of some bricks it may be desired to leave a comparativelywide blank marginal space, as at b, at the edge of the rugous effect.This can be done by adjusting the pin inwardly between the clampingplates 4;. As the pin 3 plows the ribbon adjacent to the edges of itsface, there is some liability of the corner of the ribbon being tornaway. To guard agaiirst this the marginal pin is located immediately infront of the mouth of the dieplate 2 where the .clay is held againstdisplacement by the corner of the die-plate.

On the top of the head 1 are secured the arms 6 in the front ends ofwhich is journaled the shaft 7 which can be held against rotation byset-screws passing through the bearings and impinging on the shaft. Journaled on the shaft 7 is the hanger 8, which also can be held againstturning by a set-;

screw passing through its bearing and impinging on the shaft To theouter end of the hanger is bolted the plate 9, which in its normalworking position extends over and parallel with the upp er face of theclay-rib- Lon. The arms (3, the shaft -7 and the hanger 5 form a hi ageconnection for the plate 9, and by manipulating the several setscrewsthe plate can be either turned back from the clay-ribbon, or rigidlysecured in its horizontal working position.

in the plate 9 a series of plowing pins 10 are mounted so as to furrowthe clayribbon as the latter passes beneath the plate. These plowingpins are quite numerous, but are so distributed as not to trackoneanother as they score the clay, as indicated by dotted lines in Fig.3. These pins are distributed over an extensive area so that generallythere is considerable space between any-two of them. The object of thisis to prevent the pins from tearing loose large particles of clay, whichwould happen were they grouped close togeth ar. For an instance, supposeall the pins extended across the path of the ribbon in a single linelike the teeth of a comb. The result would be l'hgi they would scrape(iii a layer of clay llw ilu fare of the ribbon to the depth which theyentered the material. As it is. the pins are being made by a particularpin will be localized adjacent to that pin, and will not extend to thedisturbance being created by the next pin. Consequently there can be nocumulative effect of several merging disturbances which would tend toisplacc largeportions of the clay. 4

Each pin 10 is adjustable in the plate 9 so that the depth of the furrowwhich it will plow can be regulated. It is seated in a threaded sleeve11 (Fig. 8) turned into the plate and is held in the sleeve by thesetscrew 12. By turning the sleeve more or less in the plate thepenetration of thepin into the ribbon can be regulated. By 1nanipulatingthe set-screw 12 the pin can be adjusted in the sleeve 11, or it can beremoved for sharpening or replacing. The furrows a, c (Fig. 2) plowedinthe upper face of the clay-ribbon by the pins 3, 10 are comparativelydeep, that is, they are considerably more than mere scratches orindentations of the material. By plowing the mate-rial in this way thereare thrown up from the face of the ribbon rows or ridges of clay instrips or particles that are more or less detached from the body of theribbon. 4

After the plowing of the material by the pins 3, 10, means are providedfor harrowing the fuIl'OVBd. face of the ribbon so as to distribute thestrips-and particles of clay in a tangled layer over the face of ther'ihon. Back of the plate 9 is the yoke 13 twig. .1) straddling the path oftravel 0 t e clayribbon; it is bolted on the table 14 that supports theribbon. To the opposite sides of this yoke are hinged the arms 15connected intermediate of their ends by the crosspieces 16. Extendingacross the free ends of the, arms 15 .is the wire rod 17. These arms 15,cross-pieces 16 and wire rod 17 constitute the harrow. In operation thewire rod rests on the face of the clay-ribbon, and

. as the latter moves along the table 14 the wire rod breaks down theridges of the furrows a,-0 in the material, and spreads the strips andparticles of clay in an even tangle over the face of the ribbon, as at,d (Fig. 2). Ordinarily the weight .of the harrow gives the requiredpressure to the operation, but should this be insufficient weights couldbe placed on the cross-nieces 16.

After the harrowing, pressure is applied to the tangled layer of stripsand particles of clay to press t e same into firm cohesion with 'thebody of the ribbon, and also to give a level surface to the broken faceof ,the ribbon. On the to of. the yoke 13 is bolted the bracket 18 ig.6) to which is so separated that the disturbance in the clay 1- peltThis roller rides upon the harrowed surface of the clay-ribbon andcompresses the tangled layer of strips and particles of clay against thebody of the ribbon, and also gives a smooth finished eli'ect to l thesurfaces of the material. By means of l l l l the hinge connectionbetween the arm and the yoke 13 the roller can accommodate itlf to anyirregularities there may be in the face of the ribbon, and it also maybe raised from contact with the ribbon for cleaning and other purposes.The roller not only evens of! the harrowed surface, but it presses thepartiolesand strips of clay into the furrows to fill the same more orless.

By means of the foregoing operation an ornamental eltect, such as at c(Fig. 2), is given to the face of the ribbon, and consequently thefinished brick (Fi 10) that simulates to a considerable extent therugous appearance of the textile rug. By varying the depth of theplowing, the pressure of the barrow and of the roller, the rugous inectcan be varied more or less to meet (liiierent l'BqllllG1'll6I1'ES.' M rThe sides of the clay-ribbon are also treated to give an ornamentaleffect. On the face of the head 1 of the machine, at each side of thedie-plate 2, is bolted the bracket carrying the plate 2i. To the inneredge of this plate is secured the sideplate (Fig. i flush with. sideedge of the mouth of the die-plate 2. In this side-plate 25 are mounteda series of pins 26, that score, as at f (Fig. 2), the side or the clayaribbon as the latter passes from the dieplate. Beyond the side-plate 25is the roller 37, also covered with sheep Pelt, to compress and smoothover "he scoring in the side of the clay-ribbon, as at g (Figs. '2,1.0). The shaft 28 of the roller 27 is journaled in i the U'SllilPQClbracket 29 pivoted on the arm i 30 secured to the table let. The tWorollers i i I I i a l l I '27 (only one is shown) are pressed againstthe opposite side of the clay-ribbon by the spring 31 connecting theupper ends of shafts 28, which extend above the plate i),

As the ornamentation on the sides of the clay-ribbon, which form theends oi the completed brick, is not so pronounced as that on the face ofthe ribbon, consequently the scoring by the pin 26 is not so deep as thefurrowing by the pins 3, 10, and it is not necessary to barrow thescored -surface previous to the action of the roller 27.

By the employment of the foregoing mechanism in the manner described anornamental brick is produced in which one of,

the faces is given the deep rugous effect of the textile fabric, and thetwo ends a: somewhat similar effect, but not so pronounced.

Having thus described my invention, what I. claim and desire to secureby Letters Patent'is:

1. The method of ornai-nenting brick to give a rugous effect to the sameconsisting in shaping the material into a clay-ribbon, plowing the faceof the clay-ribbon into comparatively deep furrows to form loosenedstrips and particles of clay on the face of the ribbon, and applyingpressure to affix the loosened particles and, strips to the body of theribbon.

2. The method of ornamenting brick to ive a rugous efiect to the sameconsisting in shapin the material into a clayaibbon, plowing t e faceof'the ribbon into.comparatively deep furrows to form. loosened stripsand particles of clay on the face oi the ribbon, harrowing the loosenedstrips and particles of clay to distribute them in an even tangle overthe face of the ribbon, and rolling the liar-rowed face of the ribbon tocompress the loosened strips and particles of clay onto the body of theribbon and t0 etl'ace the'furrows.
